Angelfish Changing Color

Angelfish has long been a favorite because of its beauty and fluid movements when it comes to aquarium dogs. And they can be quite the house pet you may be hoping for with the new variations constantly being attainable.

Do angelfish change color? Yes, they do, and it all depends on their environment, surroundings, stress level, mood, and/or spawning season. It is normal to see them change colors throughout the day, so don’t worry.

You will read in this post about how the color of an angelfish varies and what causes it.

The Science behind Their Transformation

The ability of Angelfish to modify colors depends on melanosomes and melanin development. Melanosomes are responsible for melanin synthesis, and a material that absorbs light is melanin.

The angelfish’s ultimate colors are dominated by melanosomes, which is by monitoring melanin’s motions and storage.

It means that the melanosomes have been distributed over to the melanophores as this particular stripe fades.

The more it extends, the thinner the bars get, and it will easily vanish.

The Cause of Color Change

There are various reasons why angelfish changes its color. And these are:

Their Environment

Not just for vanity, the stripes seen in the angelfish have a reason. If there is an enemy close by, it allows them to camouflage.

With that said, if there are concerns, the colors of their skin can shift. They lie flat on the bottom occasionally, play dead, and change their color to pale.

Stress is not as good for them as it is for other fish. You could remember that they didn’t look the same when you purchased them, particularly when you bought your angelfish from a pet shop.

It can be jarring and upsetting for them to switch from one living environment to another, thus the color change.

Superiority To Others

You may find that certain smaller ones change color from time to time as they meet the larger ones if you have multiple angelfish in your aquarium. It is a superiority issue.

The smaller ones owe their larger counterparts reverence and a fair measure of deference.

Their Nutrition

Food is important, particularly for aquatic fish, as they cannot search for any prey on their own.

A bad diet can influence the overall color of your angelic fish. Researchers recommend flakes and pellets because they provide the nutrients they need to survive.

The aim is to increase their consumption of nutrients so that they will get the ideal balanced body and it will reflect in their skin color.


To conclude, angelfish experiencing changes of color is not a special occurrence. It is normal, and it gives you an understanding of what’s going on with them sometimes.

There is no reason to think about it if their food consumption, pH level, and water temperature are fine.

Take advantage of these variations in coloration, and it will show you whether your fish is healthy or not.
